Some people on here know of Serenity's issues. She does well with the family she lives with at the house so I'm wondering if what she did yesterday, should I be concerned at all? Yesterday I took Serenity to the beach. When around water she can be a bit more funny about people, I really have no idea why this is but the main time I am more on edge around her is when we go to swimming spots because of how I've seen her act at times around people but giving her credit, she has also behaved a lot around people when around water. Note; I don't stay around where people are when she plays in water, it's if I've had to walk past some one to get somewhere/we've left a swimming hole because some one has come down or when I last took her to the beach and people would randomly walk past. Yesterday Serenity and I were at the beach. Rob (my step-dad) was going to come down and meet me. I saw him approaching so I stood there and Serenity was standing in front of me. No big deal till I noticed she was stiff and when Rob was a few feet away she growled at him for a moment. After that moment he talked to her, she relaxed and played with him. I would like to add she does like him but she is also a tad wary of him in general. I don't know if this should concern me at all or leave it at, possibly being around water caused this. Is it a possibility she didn't recognize him at first? Could she have recognised him but still growled? Could being around water caused this? We've seen him walking down the street towards us because and she had no problem with him. Thanks!
